change the selected option color (while its selected)

Question

When an option is selected (regardless of its color or background color), it's background will be set to blue and the font color to white. How to change these behaviors? Say I want to set the font color to red, while an option is selected.

[updated]

As far as I know, you cannot do that because it is not rendered in the browser. this is rendered by the OS. so if you want that badly, build your own or use other libraries' menus like Jquery UI's ..

Read this

Example (using jquery ui set your css to this while using menus):

.ui-widget-content .ui-state-focus{
    color:red;
    background-color:lime;
    background-image:none;
    background-repeat:no-repeat;
}
